Florida, EUA.- Astronomers discovered the brightest stellar explosion ever recorded, a supernova that exceeds by far the light of all the Milky Way.
A international team revealed Thursday in the journal Science “ supernova most powerful seen in the history human “. Astronomers used a network of telescopes around the world to detect the colossal supernova last year.
supernovas super-luminous stellar -explosiones extrabrillantes- are considered rare. The newly discovered is especially rare. Luminosity is double any observed so far
At its most intense, is thought to be 20 times brighter than the entire Milky Way. Some estimates have it 50 times more luminous
To get an idea of what it means.. It is 570,000 million times brighter than the sun
The study’s lead author, Subo Dong, from Beijing University, said that when he learned of the magnitude of the discovery last summer, was “too excited to sleep the rest of the night.” His colleague Benjamin Shappee of the Carnegie Institution for Science in Pasadena, California, did not believe the results at the beginning because it seemed “surreal”.
“Discoveries like this are the reason that I’m an astronomer,” he said Shappee in an email. “Nature is very clever and often more imaginative than we can be.”
Named ASASSN-15lh, the All-Sky Automated Survey program for supernovae, and pronounced “assassin” (murderer) the mega explosion is located in a galaxy perhaps 3,800 million light-years away. Galaxy accurate is unknown. There are other mysteries too.
